Patent CA-2264202-A1 (CA)
Title: Reverse osmosis pump and shut off valve
Inventor: YIU CHAU CHAU
IPC: B01D61/06
Filed: 1999-03-03
Abstract: In one embodiment a reverse osmosis permeate pump with shut off valve and reverse osmosis system employs bypassed feed water from the reverse osmosis membrane to drive a water wheel and gear set to reciprocate a piston back and forth between two chambers in the pump. Permeate from the membrane is introduced to the respective chambers by a pair of fluid inlets and discharged from the respective chambers through a pair of discharges to a storage tank. Flow through these respective inlets and discharges is a function of the direction in which the piston is moving and whether it is imparting a pressure or suction on a given chamber. A second piston is exposed to the pressure in the discharges from the chambers and the second piston moves between a position permitting incoming feed flow to the membrane, and a position blocking that flow upon increase in pressure in the fluid discharge from the chambers. In another embodiment, the reverse osmosis permeate pump is powered by an independent source of power. In both embodiments, the pump and shut off valve is on the permeate side of the membrane which permits a substantial reduction in pump size, and the permeate pumps and shut off valves of the invention permit substantially increased pressure drops across the membrane and increased system production capacities and rates.

Title: Video data encoder, video data encoding method, video data transmitter, and video data recording medium
Inventor: MIHARA KANJI
IPC: H04N19/136
Filed: 1998-07-01
Abstract: An encoding preprocessing section supplies a CPU (6) with a statistic amount (index data) representative of the feature of source video data to be encoded. Based on the statistic amount, the CPU (6) operates the difficulty of encoding video data and then operates a target encoding amount assigned to each picture of the video data based on the difficulty of encoding. The CPU (6) can perform encoding in real time without performing two encoding runs required for conventional two path encoding by feeding forward the operated target encoding amount to an encoder (4). Optimal encoding is realized depending on the pattern of the video data because the target encoding amount is operated depending on the difficulty of encoding the video data.

Abstract: A method and equipment for using two SIM cards with the same MSISDN number in a mobile communication system. To at least one subscriber identifier are allocated at least two identity modules (SIM), of which only one at a time can be registered as active. In connection with location updating it is checked whether the location updating relates to a subscriber identifier to which at least two identity modules (SIM) have been allocated. If yes, it is checked whether the identity module (SIM) concerned is at that particular moment registered as passive, and if yes, it is activated and the identity module (SIM) earlier registered as active is deactivated.    If the identity module (SIM) earlier registered as active is involved in an on-going call while location updating is being performed using an identity module (SIM) earlier registered as passive, the location updating is rejected or delayed until the on-going call has been terminated.

Inventor: SUNSHINE STEVEN S
IPC: G01N21/35
Filed: 1998-02-02
Abstract: A method and apparatus for continuously monitoring and measuring the concentration of gases in a gas-containing liquid such as a transformer oil. A  passive gas extractor (300) extracts via a membrane (304) dissolved gas from the liquid. The gas sensor (500) senses the concentration of a constituent gas in the extracted gas, in the presence of other constituent gases. The gas sensor (500) comprises a sample chamber (502) which receives the extracted gas, a non-dispersive infrared (IR) absorption sensing system which generates an electrical signal corresponding to the light absorption, and an electrical output comprising the electrical signal generated by the non-dispersive IR  absorption sensing system. A processor (800) receives the electrical signal corresponding to the light absorption, at the one or more specified IR  wavelengths, of the extracted gas in the chamber, and computes the concentration of at least one gas constituent present in the extracted gas.

Title: Method of playing announcements in telecommunication network exchange
Inventor: KORHONEN AKI
IPC: H04M3/487
Filed: 1999-01-25
Abstract: The invention relates to a method of playing an announcement to a call party in a telephone exchange during connection set-up. The invention is based on the idea of totally separating the detection of the need for an announcement from playing the announcement. In the invention, the need for the announcement is detected in a conventional manner at a given stage of call set-up (6.7). In the invention, however, the exchange does not play the announcement immediately, but delays playing it up to a later stage of call set-up or up to later event, if necessary (6.15). The announcement may be played, for example, not until collection of additional dialling is definitely terminated, the call is confirmed to be successful, the announcement is confirmed to be necessary/correct, and so on. As a consequence of the announcement, wrong and unnecessary annoucements and the failure of the call are thus avoided. The invention further relates to a telecommunication network exchange in which the method can be applied.

Title: Rolled shingle roofing material and method of installation
Inventor: HAMLIN H LEE
IPC: E04D5/12
Filed: 2000-03-16
Abstract: An assembly including rolled shingle roofing material that can be easily installed on a roof and a special handling tool. The tool reduces the strain of carrying the roofing material and of raising to the roof. The roofing material includes a membrane attached by pressure-sensitive adhesive to a plurality of standard flat roofing shingles so as to create a continuous array of shingles which can be formed into a roll or rolled onto a spool. This membrane also serves as a release sheet to prevent thermally-activated adhesive present on the shingles from causing them to stick together in the roll. Alternately, roofing material pre-cut with slots to resemble shingles is rolled together with a release sheet placed on the bottom of the material so as to isolate a thermally-activated adhesive applied thereto from other surfaces. In the assembly, either type of roofing material can be used with the special handling tool. This tool includes a "U"-shaped tube in which one of its branches is inserted through a hollow core formed by the rolled roofing material itself or, alternately, a hollow cylinder upon which material has been wound. The branch of the "U"-shaped tube so inserted can then be used as an attachment point for a rope, useful in raising the roll of roofing material to the roof. Or one can use the distal end of the "U"-shaped tube as a handle to facilitate carrying the rolled roofing material and placing it on the roof.
